Philadelphia is home to one of the oldest and most prestigious divisions of the American Institute of Architects.

Founded in 1869 and paying tribute to more than 300 years of architectural design in our city, AIA is representative of close to 1,500 member architects of the Philadelphia, Chester, Delaware and Montgomery counties.

The Center for Architecture performs the charitable and educational work of AIA Philadelphia and serves as the physical home for the chapter in Center City Philadelphia.

This month is a great opportunity to check out the Philadelphia Center for Architecture for yourself, as its annual exhibition celebrating the creative pursuits of architects outside of their professional studios is now on display, featuring paintings, photographs, collages, prints, sculptures and more.

All of the art that is sold during the exhibit, including special signed sketches by some of the most noteworthy architects in the field, will benefit educational programs run by the center.

The Art by Architects exhibit will run until November 16. Admission is free, and hours are Monday-Saturday, 10 a.m.-6 p.m.; Sunday, noon-5 p.m.
